Module to Remote Start, if you are using a REMOTE STARTER ONLY, use the 791, to
order go to the SECURITY BYPASS MODULES Page on this website. IF you are
installing a REMOTE STARTER with KEYLESS ENTRY you MUST USE the INTERFACE
BYPASS MODULE, Part # DB-ALL or XK09, EITHER Bypass will do the Anti-theft and
Keyless entry. To order, go to the INTERFACE BYPASS MODULE Page on this website.
NOTE #2: The IGNITION #2 wire WHITE must be connected to prevent a CHECK ENGINE LIGHT
